I use Yahoo as my homepage and access it through Mozilla. Normally it loads in mere seconds. Last night and today it is taking extremely long to load and in some cases it has timed out. When it does load, all the pictures and other features are not included and either don't load or load much later.

I tried to load Yahoo from MIcrosoft Edge and it loaded perfectly. I am assuming there is an issue with Mozilla?

Thanks for looking into this matter and letting me know.

~4/14/25 with very 137.0.1 & .2 Duolingo is unable to complete loading after sign-in. DUO owl just keeps marching - states Loading. Continues same for hour w/ o any progress. Clearing cache, reloading page or browser with same result. Sign-In then Owl marching saying loading. Works fine with Chrome. Worked fine w FF very prior to 137.0.1 64bit. Reported to Duolingo.

Firefox uses too much memory, with 1 tab 1GB+, and with 4 tabs all 3GB+, this is not normal, the forum topic did not help, reinstalled and did not help, there are no more than 6 extensions, and they consume only 160mb.

Здравствуйте. Что произошло с браузером. Почему не загружаются страницы, а открываются те, которые открывались когда-то раньше? Мне сейчас постоянно жать на кнопку обновить страницу? Что вы сделали с браузером???

When printing a web page as a pdf file and trying to import the data with Power Query, it is not able to recognize all of the data. It picks up the headers and some of the body but ignores other parts.

TikTok might not be working due to a few common reasons like a poor internet connection, server problems on TikTok’s side, an outdated app version, or too much cached data. Sometimes, the app might crash or fail to load videos properly. Restarting the app, clearing cache, or updating it usually helps fix the problem. bold text

I cannot tile my Firefox windows to left or right when I choose vertical tabs mode from settings. It works fine with horizontal tabs enabled. I am using Firefox 137.0.1 on Linux Mint 22.1 Cinnamon 6.4.8 with Linux Kernel version 6.8.0-57-generic, display server X11.

When I run firefox, the following commands lsof |grep -i firefox|grep memfd|wc -l lsof |grep -i firefox|grep memfd|grep DEL|wc -l produce values in the 20 000 or even 100 000 range.

For instance, currently with only 1 tab open - the form on which I type this question - I get $lsof |grep -i firefox|grep memfd|wc -l 19317 $lsof |grep -i firefox|grep memfd|grep DEL|wc -l 16362 And these numbers are still on the low side. In normal use (e.g., 10 tabs open), the numbers reach close to 100 000.

Some example lines of lsof: firefox 3883 135330 StreamT~s xxx DEL REG 0,1 27559 /memfd:mozilla-ipc firefox 3883 135325 Indexed~I xxx 156u REG 0,1 67108864 11945 /memfd:pulseaudio (deleted) firefox 3883 135325 Indexed~I xxx 160r REG 0,1 13192 78 /memfd:mozilla-ipc (deleted) firefox 3883 135427 StreamT~s xxx 132r REG 0,1 170 3110 /memfd:mozilla-ipc (deleted)

Although it may be a problem in lsof, this suggests that firefox performs a lot of memmaps that are later deleted, but are deleted in a way that leaves some left over state. Note that the "DEL" state in column 6 does not always agree with "(deleted)" in the right most column.

I first discovered this issue when my computer started failing with messages like pipewire-pulse[103898]: pw.mem: 0x55ce0273ac50: Failed to create memfd: Too many open files This could be a coincidence of course.

Current firefox version: 137.0 (but also occurs in other versiosn, e.g. 133.0.3) uname -r: 6.12.7-100.fc40.x86_64 OS: fedora 40
